By posting and offering a commission split you are only offering the cooperating broker's share of the commission which is traditionally 50% of the total commission the Seller is willing to pay according to your Listing or Commission Agreement.
Cooperating with other brokers and sharing commission split "opportunities" is good practice. However, especially in the case of short sales, and also in this volatile market, it is also good practice to offer a disclaimer that states "actual commission split shared is dependent on a full-price offer, and subject to Seller's final approval".
If you lead with better information you will be less likely to get caught short on your own commission. A perfect example of this is in a Short Sale a bank might decrease the commission to 5% overall upon Short Sale Approval Letter. If you offered 3% because you have a 6% Listing Agreement, you could find yourself in a dispute with the other cooperating broker demanding 3% which subjects to you 2% only.
